To reproduce, the male repeatedly touches the woman. Initially to confirm the sex, then to deposit spermatophores that will move along the female's arm and release the spermatozoa. This several times between 1m30 and 3h.
The female dies of exhaustion and hunger 10 days after the last hatching because she does not eat anymore from 2 weeks before the laying. The male dies of senescence (slowing of the vital activity) a priori because of the optical gland which controls the reproduction and whose hyperactivity after this one would trigger this decadence.
The species therefore lives between 12 to 15 months.
This species is - in addition to being remarkable for its changes of livery and texture - extremely intelligent: capable of strong memorization, decision making, emotional reactions, learning by observation and reactions of discrimination. >
Researchers also come to think that man is no longer the only conscious being and that octopus has joined this group.
Mammals have a horizontal tail.
Fishes have a vertical fin.
We can hear the bull shark is very dangerous because of attacks near La Réunion island.
However, tens of them are living at 600 feet from the famous beach of Playa Del Carmen in Mexico. And there are no attacks.
Turtles are in economy mode when they are sleeping. If they are woken during night, they may not have enough air to return to surface.
So, please be careful during night dives!
